Choosing the Right System for Inventory and Production Management

We are a small business looking to increase rolls at our company and also get more organized.  We need to roll out a better way to organize inventory - track lots of ingredients as well as finished products.  We also would like to have this program be able to support production with batch reports, shipping with picklists / pack-lists, and more.  Right now everything is done centrally and manually, through excel sheets, emails, and a lot of third part applications.  Please advise if there is a system that you can recommended that covers many if not all of these bases and is "affordable"?  

Or vise versa if your organizations have found it better to make and run in house systems.  Very eager to hear what you all think about these kind of products and solutions to organization.  

Currently looking at MRPeasy and WhereFour. MRPeasy looks very basic and just controls inventory, whilst WhereFour is very inclusive but maybe a little to much for us in both scope and price (3k installation / 800$ per month)

Thanks in advance!
